Do yourself a huge favor. Get at least one of your degrees in math education as opposed to pure math the whole way up the ladder. If you go the pure math route, I think your fears are fairly well justified. Chalk-and-talk teaching is going the way of the dinosaurs. That's what the Khan Academy is for. Go learn some of the cutting-edge teaching techniques that are being developed and you'll have a skill set that no mere computer can replace.

If you think that online learning is "simply watching" you should really have a look at the new classes on Coursera and Udacity.

While I concur that some of these do have interactive elements, many of them are of them are of the watch-this-video variety. The TED-Ed stuff which started this thread is a great example.

Of course not the cutting part.

Thank you for making my point for me. Surgeons get paid for the cutting part, not the memorization part. Likewise, mathematicians get paid for designing new applications for mathematics, not just applying pre-existing formulas. Moreover, while the online courses you mention and similar ones for mathematics (like ALEKS) can be VERY good for memorization...IF AND ONLY IF you are a motivated learner to begin with. Only a real live teacher has ANY chance of changing the mind of a student who has a "When am I ever going to need to know this" mentality.

Why would people even go to college once this becomes mainstream?

Simply put, passively watching a video is better than nothing and even better than tuning out in the middle of class. However, there is simply no replacement for hands-on experience. That's why you see all those cutting edge new charter schools that are opening up moving away from textbook-based learning to project-based learning. As a math teacher, I am 100% behind sites like this providing opportunities for people to engage in life-long learning. That being said, I simply don't believe you can become an expert anything simply by watching. The cognitive psychology research says you need something like 10,000 hours of practice to develop the automaticity of an expert. That is to say, do you want the surgeon who has to check the anatomy book before he cuts into you or the surgeon who practiced on cadavers so much he can find the place to cut with his eyes closed? THAT, my friend, is what the value of college is. The other key feature of college is that gives you a chance to see where the holes are in understanding/technology/methodology. Universities, especially at the graduate level, are really about preparing people to engage in innovation. Do some people have good ideas without college? Surely. Are even half of those ideas feasible or attainable without some serious training? I doubt it.

I think there's few key flaws with your idea.

1) The idea that data is accurate

The ad clearly states that the margin of error is more than half the size of the scale. Basically flip a coin. If it's heads add 50, if it's tails subtract 50. That's so hideously inaccurate that it's not even worth calling data. Imagine using a similar technique in measuring the temperature outside. Let see...my thermometer says 30...*flip a coin* Wow! It's 80 degrees out in December. Heat wave!

2) Data is impartial

It's not hard to pick criteria that may have some statistical correlation to student achievement that are utterly beyond the teacher's control. Why should those affect their score directly? This formula just adds a whole lot of random numbers together, including "Student Characteristics." What does that even mean? I mean, maybe if they were calculating this number through a MANCOVA or some other powerful statistical method, I could see how it would be worthwhile to account for student's being poor or whatever. However this formula relies almost entirely on addition. What? Shouldn't the "Student Characteristics" for example be a multiplicative coefficient? No. This is clearly a formula without fairness in mind.

3) It can't hurt anyone.

Politicians have been looking for ANY excuse to badmouth teachers for DECADES. Despite the very clear claims that this method is "experimental," you know it won't be long before some member of congress goes "And look at the average teaching effectiveness in New York, we should cut their funding some more" if the numbers are artificially low, those number are going to be used politically.

Imagine there was some measure of say, likelihood of being a rapist based on similarly arbitrary criteria. If your score indicated a high likelihood that you were a rapist based upon the "fact" that two of your neighbors are rapists, would you want that "data" published?

Comment Some quick math (Score 1) 397

The math behind this is totally bizarre. Twenty bucks a month for 5mbps or 60 bucks a month for 15mbps makes sense. Triple the bandwidth, triple the cost. However, add some some arbitrary all user cap of, say, 100GB per month:

5 mb/s = 300 mb/min = 18000 mb/hour = 2250 MB/hour = 2.2GB / hour.

So, about 45 hours of low speed internet for $20 dollars, but only 15ish hours of high speed internet for $60. You pay more to get less overall internet access! Only if triple bandwidth also implies triple cap does this make any sense whatsoever. Using this same logic, if you're one of the lucky few on a 50mbps connection, OF COURSE you're going to use ten times as much data as the person with 5mbps connection. Probably more, really, considering the person who wants the cheapest available internet probably doesn't use it to its full capacity. Someone needs to explain high school math to these companies. A little statistics, maybe a little calculus, and it wouldn't surprise you at all that only the very few people who buy the best internet use the most bandwidth. Gee, I wonder who's going to use more water, the single bedroom home or the big restaurant down the street?

Submission + - Are Small Rocky Worlds Naked Gas Giants? (discovery.com)

astroengine writes: "The "core accretion" model for planetary creation has been challenged (or, at least, modified) by a new theory from University of Leicester astrophysicists Seung-Hoon Cha and Sergei Nayakshin. Rather than small rocky worlds being built "bottom-up" (i.e. the size of a planet depends on the amount of material available), perhaps they were once the cores of massive gas giant planets that had their thick atmospheres stripped after drifting too close to their parent stars? This "top-down" mechanism may also help explain how smaller worlds were formed far from their stars only to drift inward toward the habitable zone."

Comment An teacher's opinion (Score 3, Interesting) 511

I learned how to use DOS at the same time I learned how to read. In fact, some of my earliest memories include a luggage-sized computer with a three-inch monochrome monitor. Today, I spend the vast majority of my free time at my computer desk. I can program in several computer languages. My desktop dual-boots 64-bit versions of Windows 7 and Ubuntu 10.4, and I am even typing this essay on an ergonomic keyboard that I brought from home. I am, to use a term coined a decade ago, a digital native. So, when I look at the state instructional technology today, I am both impressed at the technological progress over the course of my lifetime and utterly disgusted by the shortcomings of its implementation in our society.

Foremost among my concerns is the mind-boggling disparity in access to technology, particularly across socio-economic status. I can point to you on a map two schools within mere miles of each other where one has SMART boards in every classroom and the other did not even have a classroom set of calculators available to me as a math teacher. That is only just digital technology. On a far more fundamental level, I can point to a different set of two nearby schools where one has automatic-flush toilets and the other had such frequent plumbing problems to a point that drinking from the water fountain was risky business. I simply do not feel that I can ethically spend time researching Facebook or the iPad as instructional technologies when not every student in the public education system has access to comfortable and healthy analog technologies like air conditioning.

Another issue that gives me significant pause is Mooreâ(TM)s Law. Technology is advancing at a prodigiously exponential rate, to the point that futurists predict an upcoming event dubbed the Singularity at which technology will progress faster than society can cope with its evolution. I am particularly fond of a TED talk given by Ray Kurzweil on the topic of the integration of technology with the body, particularly the part on an already-possible synthetic red blood cell which would, to paraphrase Kurzweil, allow the average teenager to regularly outperform todayâ(TM)s Olympic athletes. Even the advent of internet-enabled phones has caused notable distress among teachers. I can not even imagine the discord when the technology is implantable and can not be turned off or confiscated. On the other hand, the standardized management paradigm behind the OGT and the SAT would finally collapse, so it would not be all bad. I digress.

Looking only at today, I question why the research on technology on Second Life as an educational venue is only in its infancy when that particular medium has begun to be replaced by other, newer alternatives like Free Realms. Similarly, Facebook is being replaced by Twitter and Diaspora just as Facebook replaced MySpace replaced Livejournal replaced Xanga replaced Geocities. Honestly, Facebook is so passé that even governmental agencies have investigated its use. I forget which one, but just a few months ago around ten red balloons were placed at random locations across the continental United States. All of them were found within about eight hours. My point is that research that focuses on a specific technology in response to a cultural fad is doomed to failure from the start. By the time anything practical made its way to teachers, students would already be offended by the outdatedness of it.

The third problem that I have with instructional technology is that there is far to much emphasis on innovation and far too little on revision. Take the TI-nspire. Look, it now includes a computer algebra system but has a terrible user interface, and just as math teachers were starting to get comfortable with the idea of allowing graphing calculators in the classroom, we have made the technology even more powerful â" re-emphasizing the original concerns about the calculators doing all the work. Similarly, take all these new educational iPad apps on top of the virtual manipulatives that you already do not know how to properly utilize in the classroom. I am vexed by the reckless abandonment of old technology for the new, and I find it hard to believe, with a culture of such technological impulsivity, that anybody was surprised when the first teacher lost a job for a social networking post. Even I do good research with good technology, the educational culture is simply not ready for mature discussion of the matter, much as Behaviorist-era America was not ready for Piaget. The whole thing just needs to sit for a decade or two.

Fragmentation is a fourth issue that makes me unwilling to enter the instructional technology field. I refer to both cultural and technological cliques. Part of what makes the Internet such an attractive place is that you can always find like minds. If you are a Buddhist, you can talk to other Buddhists even if another is not physically present within a fifty mile radius. On the other hand, if you are a bigot or an awkward geek with bad social habits, those can be reinforced just as easily. In fact, if you really wanted to, you could spend your entire time online with only people who generally agree with you. As someone who believes that there is much beauty to be found in diverse cultures as well as much benefit in their intermingling, the idea of everyone going to online schools that are homogenous is a nightmarish dystopia.

On the technological side, while there is a reasonable amount of similarity in feature sets between competing technologies, the intellectual property culture in which companies operate encourages significant differences in availability and implementation. The research on one piece of software or hardware may not apply to others. It would be easy for a practitioner to see an article praising the Sketchpad, and try a cheaper alternative only to find that it is not as good as the article made Sketchpad. However, many teachers in that position might simply abandon all geometry packages as equally useless in their ignorance of the technical difference between the various pieces of software.

Even if every teacher had access to an equal amount of technology, my concern is that, as a teacher educator, I feel that I would be unable to adequately prepare them to cope with all the variation available without giving them an extensive amount of technology training that simply is not feasible in the one or two courses they might take on the subject for their certification. I will concede that the mathematics-specific technology base is much smaller, but I am not sure how I can teach someone how to differentiate, for example, between ALEKS and The Academy of Math or how to decide whether or not to use a calculator in a given lesson other than on terms of general pedagogy that could easily be applied to various manipulatives in similar situations. Even the course I took here just a short time ago seemed to rely heavily on the judgment and experience of the individual teacher. Certainly, the literature was useful in convincing people that technology was not necessarily harmful, but there was an explicit assumption that I, as a student, already had a good understanding of point-and-click, etc. I guess, what I am saying is that research on instructional technology is a lot like research on a textbook. There are just too many options for it to be useful to the practitioner, and the important part is how it is used more than what it has.

The last concern that I will talk about is the conception of technology as teacher-proofing the curriculum. At a superficial level, this can be seen in the appeal of online schools. As an administrator, it is cheaper and more efficient because all my teachers will teach the exact same thing and I can probably even get by with fewer teachers. As a student, I do not have to really interact with my teacher or my peers, and nobody can stop me from taking my test with the textbook open. The teacher in this scenario can become little more than a glorified computer lab supervisor. On a more insidious level, technology gives administrators the ability to say, âoeIâ(TM)ll spend my money on more gadgets and gewgaws and that will make the teachers betterâ instead of âoeIâ(TM)ll spend my money to help my teachers collaborate and improve themselves professionally.â Technology is a concrete âoeimprovementâ that is easy to justify to parents and school boards. Unless the administrator already believes in the teachers as professionals, technology is just one more reason that he or she can believe otherwise.

To summarize, I see the technology as too rapidly evolving, the American populace as too enamored with the bleeding edge and access as too inequitable across populations.

While what Watson represents is a huge leap forward in AI, ultimately it's not much different than some of the better chat bots. The only difference now is a massively better database from which to query. While the ability to "understand" idiosyncratic speech, such as puns, will merge nicely with speech recognition softeware that already exists so that you can now use "Call mother" and "Call mom" interchangeably without programming those specific phrases, it is nothing like true intelligence. Some thoughts.

1) Can Watson MAKE even the most rudimentary puns just because it can process them? Call me when a computer comes up with something even as dreadfully literal as "Want to hear a dirty joke? A pig fell in the mud." The creation of puns requires the creator to have some sort of theory of mind of the listener. Statistics does cool things, and may eventually inform a computer that algorithmically generated statements that contain references to farts are generally received as "funnier," but that is about it.

2) The response about Wonder Woman being the first woman in space is a crucial component to intelligence. It's all just data to Watson. Until we can really define what makes Wonder Woman fictitious, Mark Twain fictitious and Samuel Clemens real, Watson ain't got a prayer in the world. Hell, real live people have trouble telling when Stephen Colbert is being himself or his person. How do you let one of Watson's descendants participate in socially constructed reality?

3) How do you explain in rules that "1+1=2", "one cow meets another cow is two cows," and "A day after a day from now is two days from now" are all the same class of statement? We don't even really know how humans make some of these incredibly simple relationships.
